What Is Threshing And How It Is Done?

Agriculture is the most important activity for the survival of mankind. It incorporates several processes. One of the major processes that are a part of the agriculture practice is threshing. It is extremely important for achieving the edible part of the crop.

Why threshing of crops is required?

Looking historically, threshing serves as a highly time-consuming agriculture practice performed by the farmers. It requires a lot of manual effort. At the core, this process involves the separation of the edible component of the crop from the chaff (the part that surrounds the crop but is not edible). Let's find out in detail what is threshing and how it is done. This particular procedure is just the component of the harvesting technique, which is performed towards the end of the harvest. Although, both the techniques as well as the technologies vary greatly throughout history, the core principle of the process remains always the same. It is agitating the crops and at the same time separating the grains from all the chaff.

Let’s Find Out What Is Threshing & How It Is Done:

Threshing process

The thresher component is the crux of the combine harvester. Despite the nature of machinery, the main function is to carry out the separation of the kernel from the cob. This is through friction. The grains are processed to a high extent. The working mechanism is through the rotation of the threshing drum which is related to the fixed concave part. The rasp bars are existing in top condition. It is combined with the adaptive concave part. It will be ensuring the optimal separation of grains.

The threshing unit comprises two main components:

• Cylinder

• Concave

This particular procedure is being accomplished through the impact of the rotating pegs, being mounted on the cylinder. This is over towards the ear heads. This component is forcing out the grains from the sheath that holds it.

Working Of Thresher

• First of all, the crop is fed into the threshing cylinder. This particular cylinder comprises the spike/ bars or even wire loops that are present around the periphery. It is dependent upon the nature of the thresher.

• Below this particular threshing cylinder, the concave is present. It is covering the lower part of the cylinder.

• The cylinder rotates at an elevated speed and the threshing of the crops takes place. The entire portion of the threshed material is falling from the concave towards the cleaning system's top sieves.

• The reciprocating movement of the top sieves facilitates the light material to be collected upwards and heavier grains fall towards the bottom of the sieves.

• Also, the sieves will be further facilitated in the grain cleaning. As it will be allowing the overflowing of the heavier straw.

Conclusion

The utilization of the latest techniques & technology during the agriculture practice undeniably yield the best outcome. Today a large number of farmers utilize the combine concave for increasing the cultivation rate. The machine undeniably paves the way for high-quality crop production under various conditions all over the world.
